A metal air battery cell has a sealed pouch defined by a metallocene film and a gas and liquid impermeable flexible layer, and an electrochemical cell contained within the pouch. The metallocene film and gas and liquid impermeable flexible layer are sealed to each other and around the electrochemical cell.

Pouched metal-air battery cells

A metal-air battery cell includes an electrode assembly and a sealed pouch. The electrode assembly includes an air electrode, a negative electrode, a separator in contact with and disposed between the electrodes, and a hydrophobic gas diffusion layer in contact with a side of the air electrode opposite the separator. The pouch envelops the electrode assembly and contains an electrolyte therein. The pouch is defined by a gas permeable hydrophobic flexible layer in contact with the hydrophobic gas diffusion layer. The electrode assembly further includes a terminal extending from and away at least one of the electrodes, and through the pouch. Opposing sides of the pouch are sealed to each other and around the terminal.
